concept phone with only a touchscreen for UI

[Dylan McCall]

Hey, nice to see this discussion! I've wondered about this before, too :)
A touch screen thimble, or a thing embedded in the end of a stylus, would
allow for tactile feedback while also supporting an existing necessary
feature (that is, touching a touch screen without smudging it, or at least
writing accurately / naturally on a touch screen).
A minor wiggle is good enough, since fingers are pretty sensitive, and it
only really has to be a suggestion.

Good idea, Matthew! (I may have to try this myself...)

There is also the device itself vibrating, of course, which is practically a
required feature for a phone anyway. The two forms of feedback could maybe
be combined for an interesting effect.

As for the original topic of a full touch screen UI (which I, at least one
North American, love! I think those tiny keyboarded devices look ridiculous
-- they're hardly tactile because they are so small)... what would be
/extremely/ cool is tapping the touch screen to turn the device on, removing
that pesky power button. I wonder how / if that could ever be possible?
(Of course the touch screen isn't your usual button, so probably can't do it
at all easily).

Bye,
-Dylan McCall

PS: Thanks for telling me I sent this the wrong way, Jon.
